They're really becoming more humid, looks the heat has stabilized since 2010, it hasn't gotten any hotter than it was that year and plateaued lower than 2010 (but higher than it was in the 2000s)....some of this seems to be cyclical since the 1990s were hotter....think of all the 90 degree records we set in the 1990s (1991, 1993, 1995, 1999 were all amazingly hot).
